Michael Avenatti said he has 'significant evidence' that Brett Kavanaugh participated in sexual misconduct in high school

The attorney Michael Avenatti claimed on Sunday that he had "significant evidence" that Brett Kavanaugh, the Supreme Court nominee, participated in sexual misconduct in high school.

Avenatti said he had evidence that at multiple house parties in the early 1980s, Kavanaugh and his friend Mark Judge would target women using alcohol and drugs "in order to allow a 'train' of men to subsequently gang rape them."

Also on Sunday, The New Yorker published an article detailing an allegation from Deborah Ramirez, who said Kavanaugh exposed himself to her at a party when they were students at Yale University.

The attorney Michael Avenatti added to the sexual-misconduct allegations against Brett Kavanaugh on Sunday, claiming he has "significant evidence" that the Supreme Court nominee participated in sexual misconduct in high school.

In an email to Mike Davis, the chief counsel for nominations for the Senate Judiciary Committee, Avenatti said he had evidence that at house parties in the early 1980s, Kavanaugh, his friend Mark Judge, and others would target women using alcohol and drugs "in order to allow a 'train' of men to subsequently gang rape them."

Avenatti told Politico later on Sunday that he represented a group of people who could corroborate allegations involving Kavanaugh and Judge. He described one of the people as a victim and the others as witnesses.

Later this week, Christine Blasey Ford is set to testify in open court about her allegation that Kavanaugh sexually assaulted her while they were in high school. Ford has said Judge was a witness to it.

Kavanaugh has denied both Ramirez's and Ford's allegations.

Avenatti, who also represents the adult-film actress Stormy Daniels in her lawsuit against President Donald Trump, said he "will be demanding the opportunity to present testimony" to the Judiciary Committee, which is overseeing Kavanaugh's nomination proceedings.
